SiO x ‐modified porous biocarbon (C/SiO x ), derived from shaddock peel through pyrolysis reaction, has been explored as an anode in rechargeable lithium batteries. The hierarchical structure endows the C/SiO x composites ultrahigh specific capacity and high electronic conductivity. After 100 cycles, a reversible capacity over 740 mAh⋅g −1 can be obtained at a current density of 0.358 A⋅g −1 . An acceptable capacity of 82 mAh⋅g −1 can also be exhibited by withstanding a current density of 17.9 A⋅g −1 . The study demonstrates that C/SiO x composites can be employed as a potential anode for advanced Li‐ion batteries.
